To provide a display unit that appropriately detects scan light.SOLUTION: A display unit comprises: a light source device that has a light source element, and when the light source element is supplied with a current and lighted up, emits a laser beam output from the light source element; a scanning unit that displays an image with scan light obtained by two-dimensionally scanning the laser beam; and a light detection unit that receives the scan light. The display unit can execute time control of controlling received light quantity that is the quantity of light received by the light detection unit, with a time interval to light up the light source element while a predetermined amount of the current is supplied thereto, and the time interval when scanning the light detection unit is different according to the received light quantity.SELECTED DRAWING: Figure 17

    【課題】適切に走査光の検出を行う表示装置を提供する。【解決手段】光源素子を有し、電流が供給された前記光源素子が点灯して出力されるレーザ光を出射する光源装置と、前記レーザ光を二次元走査した走査光により画像を表示させる走査部と、前記走査光を受光する光検出部と、を有し、前記光源素子に所定の電流量が供給された状態で点灯させる時間間隔によって前記光検出部が受光する光量である受光光量を制御する時間制御を実行可能であり、前記光検出部を走査するときの前記時間間隔が、前記受光光量に応じて異なる表示装置である。【選択図】図17
